The only thing Horizons had going for it was more prevalent, steeper, sharper turning canyons for racing and hooning opportunities (a niche, though fun, activity), and more mountains like this on higher G planets where it didn't make sense.
I'm sorry Horizon's stalwarts, but that's just bland to me now. But yes I concede that it is different and change is hard.
The only thing I wish for is geological sciency gameplay. Every planet has something interesting I'd like to drill, sample and crack open, just like Curiosity on Mars.
